Exponentiation seems broken?

Hey @printfn, really cool project!

I've been looking for a Rustier version of sharkdp's insect for a while, so I'm glad this showed up :D

Steps to reproduce error

I'm trying to reproduce the good old trig identity of sin²(x) + cos²(x) == 1 but something seems off:

> x = 2
2
> sin(x)**2 + cos(x)**2
approx. -1.4104461161
> sin(x)^2 + cos(x)^2
approx. -1.4104461161
> sin(x)*sin(x) + cos(x)*cos(x)
approx 1

Happens on latest main and also on the WASM build on GitHub Pages

Thanks for the report! This bug is caused by incorrect operator precedence handling. For example, (sin x)**2 + (cos x)**2 does produce the correct result of 1. It's related to issue #76.

Oooh, got it

In this case I'll close this one as a duplicate of #76
